Repetitive Acoustic Streaming Patterns in Sinusoidal Shaped Microchannels
Geometry of the fluid container plays a key role in the shape of acoustic streaming patterns. Inadvertent vortices can be troublesome in some cases, but if treated properly, the problem turns into a very useful parameter in acoustic tweezing or ...

Characterization of Acoustic Streaming in Gradients of Density and Compressibility [PDF]
Suppression of boundary-driven Rayleigh streaming has recently been demonstrated for fluids of spatial inhomogeneity in density and compressibility owing to the competition between the boundary-layer-induced streaming stress and the inhomogeneity-induced

Frequency dependence of microflows upon acoustic interactions with fluids [PDF]
Rayleigh surface acoustic waves (SAWs), generated on piezoelectric substrates, can interact with liquids to generate fast streaming flows. Although studied extensively, mainly phenomenologically, the effect of the SAW frequency on streaming in fluids in ...

Theoretical and experimental characterizations of gigahertz acoustic streaming in microscale fluids
Even as gigahertz (GHz) acoustic streaming has developed into a multi-functional platform technology for biochemical applications, including ultrafast microfluidic mixing, microparticle operations, and cellar or vesicle surgery, its theoretical ...

Frequency effect on streaming phenomenon induced by Rayleigh surface acoustic wave in microdroplets [PDF]
Acoustic streaming of ink particles inside a water microdroplet generated by a surface acoustic wave(SAW) has been studied numerically using a finite volume numerical method and these results have been verified using experimental measurements. Effects of
